79990252 divided by 431 
Let's see how many times 431 fits into 79990252.

On to step 1:
If we divide 7 by 431, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 431

On to step 2:
The number 431 fits into 79 0 times, leaving a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Fetch the next digit (9) from the dividend, attach it to 79 and continue: 799 / 431

Step 3:
431 goes into 799 1 times with a remainder of 368.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 431 away from 799, we end up with 368.
Take the next digit (9) from the dividend and append it to 368, then repeat: 3689 / 431

Let's proceed to step 4:
3689 divided by 431 is 8 with a remainder of 241.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we subtract 3448 from 3689, we get 241.
Append the next digit (0) from the dividend to 241 and continue with: 2410 / 431

Going ahead to step 5:
When dividing 2410 by 431, we get 5 with a remainder of 255.
Put 5 as the next digit of the answer. 
Result so far: 185.0
Deduct 2155 from 2410 and we're left with 255.
Fetch the next digit (2) from the dividend, attach it to 255 and continue: 2552 / 431

Going ahead to step 6:
431 goes into 2552 5 times with a remainder of 397.
Write down 5 as next digit of the result. 
Result so far: 1855.0
Subtract 2155 from 2552 to get 397.
Take the next digit (5) from the dividend and append it to 397, then repeat: 3975 / 431

Moving on to step 7:
If we divide 3975 by 431, we get 9 and a remainder of 96.
Put 9 as the next digit of the answer. 
Result so far: 18559.0
Deduct 3879 from 3975 and we're left with 96.
Grab the next digit (2) from the dividend, add it to 96, then carry on: 962 / 431

Moving on to step 8:
962 divided by 431 is 2 with a remainder of 100.
Put 2 as the next digit of the answer. 
Result so far: 185592.0
If we subtract 862 from 962, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 9:
431 goes into 1000 2 times with a remainder of 138.
Record the quotient 2 as the next digit in the result. 
Result so far: 185592.2
Subtracting 862 from 1000 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 10:
431 can be fit into 1380 3 times, resulting in a remainder of 87.
Use 3 as the next digit of our solution. 
Result so far: 185592.23
Subtracting 1293 from 1380 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 11:
If we divide 870 by 431, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 185592.232
If we subtract 862 from 870, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
431 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 185592.232
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
431 goes into 800 1 times with a remainder of 369.
The next digit of our result is 1. 
Result so far: 185592.23201
Subtract 431 from 800 to get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Moving on to step 14:
3690 divided by 431 is 8 with a remainder of 242.
Use 8 as the next digit of our solution. 
Result so far: 185592.232018
Subtract 3448 from 3690 to get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 15:
If we divide 2420 by 431, we get 5 and a remainder of 265.
The number 5 becomes the next digit in our result. 
Result so far: 185592.2320185
Deduct 2155 from 2420 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Going ahead to step 16:
431 goes into 2650 6 times with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 185592.23201856
Subtracting 2586 from 2650 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 185592.23201856 and a remainder of 6.4e-08.
